34 ATP molecules are produced from one glucose molecule during the electron transport chain
The correct answer is: sea stars
All animals listed above are invertebrates. One of the characteristic of invertebrates are that they are protostomes with the exception of Echinodermata (sea stars). The difference between protostomes and deuterostomes is in their embryonic development (orgin of mouth and anus).
In protostomes the mouth forms first: the oral end of the animal develops from the first developmental opening. On the other hand in deuterostomes the first opening (the blastopore) becomes the anus, and the oral end of the develops from the second opening.
Humans are also deuterostomes.
Answer:
The correct answer will be option-B
Explanation:
Meiosis is a way of cell division used by the organism to produce a large number of cells from a few parent cells. This is used to make the gametes of the body.
Meiosis produces four daughter cells from a single parent cell in two stages that is meiosis I and II. Each stage proceeds in four phases- prophase, metaphase, anaphase and telophase.
The reduction division of the chromosomes or the ploidy number takes place during anaphase I of meiosis I and not prophase I which is the initial phase of the division. Therefore, during prophase I the chromosome number of the cell remains the same.
Thus, Option-B is the correct answer.
Answer:
Explanation:
Chlorophyll pigments (mainly chlorophyll a and b) absorb the red and blue spectrum of visible light in the electromagnetic spectrum for photosynthesis. This is why leaves appear green (and occasionally orange) because this visible light portion is not absorbed. The blue light absorbed by leaves ranges between 400 – 450 nm while the red light ranges between 500 nm and 700 nm.
Answer:
A. If errors are not removed from areas with a gene, then the resulting proteins could be affected.
Explanation:
Since the genes in DNA contain instructions for the synthesis of proteins, any mistakes in areas of a gene will change how proteins are made.
It is important for cells to perform checks in order to catch these mistakes, because otherwise, RNA will be carrying the wrong instructions to create a protein.
